A Study of Geometry in Anisotropic Quantum Hall States by Principal Component Analysis
Na Jiang, Siyao Ke, Hengxi Ji +3
In the presence of mass anisotropy, anisotropic interaction, or in-plane magnetic field, quantum Hall droplets can exhibit shape deformation and internal geometrical degree of free…
A Particle-Hole-Symmetric Model for a Paired Fractional Quantum Hall State in a Half-filled Landau Level
William Hutzel, John J. McCord, P. T. Raum +4
The fractional quantum Hall effect (FQHE) observed at half filling of the second Landau level is believed to be caused by a pairing of composite fermions captured by the Moore-Read…
Fractional quantum Hall states in two-dimensional electron systems with anisotropic interactions
Hao Wang, Rajesh Narayanan, Xin Wan +1
We study the anisotropic effect of the Coulomb interaction on a 1/3-filling fractional quantum Hall system by using an exact diagonalization method on small systems in torus geomet…
Models of Strong Interaction in Flat-Band Graphene Nanoribbons: Magnetic Quantum Crystals
Hao Wang, V. W. Scarola
Graphene based nanostructures exhibit flat electronic energy bands in their single-particle spectrum. We consider interacting electrons in flat bands of zig-zag nanoribbons. We pre…
Identifying Quantum Topological Phases Through Statistical Correlation
Hao Wang, B. Bauer, M. Troyer +1
We theoretically examine the use of a statistical distance measure, the indistinguishability, as a generic tool for the identification of topological order. We apply this measure t…
Jastrow-Correlated Wavefunctions for Flat-Band Lattices
Hao Wang, V. W. Scarola
The electronic band structure of many compounds, e.g., carbon-based structures, can exhibit essentially no dispersion. Models of electrons in flat-band lattices define non-perturba…
Particle-Hole Symmetry Breaking and the 5/2 Fractional Quantum Hall Effect
Hao Wang, D. N. Sheng, F. D. M. Haldane
We report on the study of the fractional quantum Hall effect at the filling factor 5/2 using exact diagonalization method with torus geometry. The particle-hole symmetry breaking e…
